This so-called wind power station is actually the "big windmill" that everyone knows. A motor is installed in the windmill. When the desert wind blows, it will push the blades on the wind power station (so these blades must be both light and strong) to rotate, providing heat to the motor, and then converting the heat. This is the entire process of wind power generation. But building this wind power station also requires certain skills. The blades of the windmill cannot be too heavy, otherwise the wind may not be able to push the windmill. At the same time, the blades need to be very strong, otherwise the sand mixed with the wind in the desert It will definitely break the leaves. At the same time, the part below the wind power station must also be very strong, because we all know that the power of sandstorms is very huge. If the wind power station is not built well, it is likely to be blown away by the sandstorm.
Therefore, we must not only discover energy, but also protect energy and create a beautiful "global village" with our hands!
The wind energy utilization coefficient of the wind turbine is expressed by CP. Theoretically, the CP will not exceed 0.593. The maximum power generation efficiency of the current mainstream wind turbines (the highest utilization rate is around 10 meters/second) is generally around 0.45, while the seven The level wind is 14-17 meters/second, which exceeds the troublesome wind speed of the fan, and the utilization rate will begin to decrease, around 0.2-0.4. The sweep area is related to the impeller diameter. The current mainstream impeller diameters are 70, 80, 93, 105, 115 meters, etc. You can calculate the corresponding sweep area.
In addition, the current mainstream wind turbine power is 1500, 2000, 3000, 5000, 6000KW, etc., of which 1500 and 2000 account for 80%.
